IMPROVEMENT IN CHECK-ROWERS FO R CORN-PLANTERS.

Specification forming part of Letters Patent No. 180,846, dated August8, 1876; application filed March 25, 187 6.

To all whom it may concern:

Be it known that I, J oHN B; GoNN, of Hackney, in the county of Morganand State of Ohio, have invented a new and valuable Improvement inCheck-Bower for Corn-Planters; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a plan view of mycheck-rower, and Fig. 2 is a front elevation thereof; and Fig. 3 is adetail view.

The nature of my invention consists in the construction and arrangementof a check-rower, as will be hereinafter more fully set forth.

In the annexed drawings, A represents the main frame, supported upon twowheels, B B, which are mounted upon short axles a a, and on each axle isa cog-wheel, G, which may be made movable, to be thrown in and out ofgear with the driving-wheel by means of a lever (not shown in thedrawings) suitably arranged for that purpose.

- The cog-wheels C C mesh with pinions b I), placed upon the ends of ashaft, d, having its hearings in boxes secured to the main frame, and onthis axle or shaft is secured the camwheel D. This wheel has a deepcircumferential groove, d which is made gradually narrower, until, atits narrowest portion, it branches toward both sides around a triangularblock, d placed thereon. In this groove work the rear ends of twopivoted levers, E E, the front ends of which are pivoted to the ends ofthe dropperslides G G, working in the corn-boxes H H. As the cam-wheel Drevolves, the rear ends of the levers E are drawn closer"together by thegradually-diminishing groove al and as the block d reaches the leversthey are thrown outward, causing the slides G G to be suddenly drawn tothe proper position for dropping the corn.

On the sides of the wheel D are circular flanges h, each having anopening, h, opposite the cam d in the groove of the wheel. Each flangeoperates upon the rear end of the lever I, the front end of which ispivoted to and operates the inner end ofa lever, J.- The outer end ofthis lever has a plunger-rod, m, pivoted to it, and at the lower end ofsaid rod is pivoted the shoe n.

K is a platform or bar secured to the main frame A, and supporting thecorn-boxes H H, as well as suitable posts, in which the levers I I and JJ are pivoted. At each end of the bar K is a guide, p,'for the passageof the rod m. As the wheel D revolves, the flanges it hold up the rearends of the levers I, depressing the inner ends of the levers J, andthereby holding the shoes at up from the ground; but when the openings71. in said flanges reach the levers, the shoes at once drop down oftheir own weight, marking the ground at the same time as the corn isdropped, as above described, and on a line therewith. The levers I are,however, immediately acted upon by the flanges h, to raise the shoes andprevent them from dragging on the ground.

In a full-sized machine the pinions b will be connected with the shaftcl by ratchets, so that the wheel D may be turned backward, ifnecessary, to set the machine so as to drop properly.

L represents a cam-wheel, to be put in place of the wheel D fordrilling, when such is desired.

What I claim as new, and desire to secure by Letters Patent, is-

The wheel D, provided with the gradually contracting circumferentialgroove (1 triangular block 01 and circular side flanges h, with openingsh, in combination with levers E, dropping-slides G, leversI I J J, rodsm, and shoes n, all constructed and arranged to operate in the mannerand for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
